Application December 24, 1940, Serial No. 371,540

(Cl. lOl-328) 3 Claims.

The present invention relates to improvements in a stamp roller and itconsists of the combinations, constructions, and arrangementshereinafter described and claimed.

An object of my invention is to provide a stamp roller in which springmeans is used for yieldingly holding -a roller away from an inking padWhile the device is not in use. The spring means isweak enough to permitthe roller to move into contact with the inking pad when the handle ofthe device is manually grasped and sufcient pressure applied forsimultaneously moving the roller over the material to be printed and forbringing the roller into contact with the pad so that the roller willtransfer the ink from the pad to the material.

One or more rollers may be used and mounted on a common axle and aseparate inking pad is provided for each roller. It is also possible touse one roller and form annular grooves in its periphery, the groovesseparating the roller periphery into circumferential surfaces equal innumber uto the pads. The padsV may be saturated with different coloredinks and these varied colored inks will cause the rollers or rollerportions to produce printed matter on the material in these colors. Thedevice may be used for design work such as making borders or it may beused for printing legends on an envelope or the like, such as forexample Air Mail.

I further provide novel means for removably supporting an auxiliaryinkingr pad and by the simple insertion of this pad into the device Icause an extra'roller or roller portion to start printing on thematerial when the device is moved thereover. l

Other objects and advantages will appear in the following specification,and the novel features of the device will be particularly pointed out inthe appended'claims. f

My invention is illustrated in the accompanying drawing forming a partof this application, in which:

Figure 1 is a side elevation of the device illustrated on an enlargedscale, portions being shown in section for clarity; y

Figure 2 vis a section along the line II-II of Figure 1;

Figure 3 is an isometric view of the auxiliary inking pad;

Figure 4 is an isometric view of the axle;

Figure 5 is an isometric View of the inking pad carrying casing; and

Figure 6 is a section along the line VI-VI of Figure 2.

While I have shown only the preferred form of my invention, it should beunderstood that various changes or modifications -may be made Within thescope of the appended claims without departing from the spirit of theinvention.

In carrying out my invention I provide a frame indicated generally at Aand shown on va greatly enlarged scale in Figs. 1 and 2. The frame A hasa top plate I, sides 2 and 3, and a front wall 4 of the shape shown inFig. 1. The wall 4 has an elongated Yopening 5 near its upper portionfor a purpose hereinafter described. It will be noted from Fig. 1 thatthe frontwall 4 has its lower edge 6 terminating above the lower edgesof the side walls 2 and 3. The rear of the frame A is open in order topermit ready access to the interior thereof. y

Within the frame A, I mount an ink pad carrying casing B and theparticular shape of the casing is illustrated in Fig.` 5. In this ligurethe casing B is shown yin an inverted position-from that illustrated inFigs. 1 and 2. The casing B has a flat wall 'I that bears against theunder surface of the plate I. The two ends 8 and 9 of the wall 'I arebent back upon themselves at I0 and II and are spaced from the wall 'Ito form arcuate portions. The ends 8 andv 9 are again bent at I2 and I3and extend toward the plate I to form opposed walls I4 and I5. The

vside walls I6 and I1 of the casing B are shown in Figs. 2 and 5 and areintegral with the wall 1. The walls I6 and I'I have arcuate edges andcooperate with the walls I4 and I5 to receive inking pads.

The portion of the Wall I lying between the opposed walls I4 and I5 hasstruck up portions I8 and I9 which cooperate with the side walls I6 andII to form three compartments C, D, and E. Within the compartment C, Imount van inking pad F and this pad has a base 20 and an inking portion2I. In the compartment E, I mount a similar pad G and this pad has abase 22 and an inking portion 23. 'I'hetwo pads F and G may bepermanently secured in the casing B, see Fig. 2l. A removable inking padI-I is depicted in Fig. 3 and this pad is removably disposed in thecentral compartment DI. The pad I-I has a channel-shaped member 24 andthe ends 25 and 26 of the member carry knob-like projections 21 and 28,see also Fig. 1. The walls I4 and I5 are provided with indentations 29and 36 for receiving the projections 2'I and 28 respectively. In thisway the inking pad I-I is removably heldin the compartment D. The end 26of the pad H carries a projection 3I which maybe manually moved to aidin removing the pad from the compartment.

I will now describe the roller construction. The frame A rotatablycarries a roller J. This roller is mounted on an axle K so as torotatethereon and the axle is held against rotation by pairs of grooves 32 and33 which slidably re- 3l are deep enough to cause the outer Aends (of`the axle to at all times lie ush with the sides 2 and 3 of the frame.

I provide yielding meansjor holdingtheaxle J is spaced from these pads.

arrangement of the parts when the device is not is slidable therein. Thefinger 60 is carried by a screw 6| which is adjustable in a slot 62,formed in the base of the channel. 'I'he finger 60 has a spring portion63 that rides on the material to be printed, the material beingindicated at 64. The nger 6|] rides along the edge 65 of the materialand causes the roller J to move in a line parallel to this edge.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

In Figs. 1 and 2, it will be noted that all three inking pads aredisposed in place and the roller Ihis is the normal Y inuse. When thedevice is used, the handle L is K in the lower ends of the slots 34 and35. and

thus keep the roller J away from the inking pads. Thismeans-consists'lof coiledzsprings 49 and 4I which have one; of theirends lformed -in-to frings and received in the annulargrooves -38fand-39 respectively. The-oppositeV ends of .-the-spri ngs are passedthrough'vopenings `42 and 43 'inthe sides 2 -and 3 vand are bent seasto-:engage-with outwardly extending anges '.44 and .45 that 'areintegral with thesides. e Spacing :cellars-.46 vand 41 are mountedon theaxle and are disposed between'the ends ofthe roller J and the sides Zand3.

The 'roller has raised)l peripheral por-tions '48; 49,

and .'50 that Yare 4separated ifrom, eachother by grooves 5|' and 52.-The -raisedportions 148549, and 59- are in alignment.- with fthe inkingpads F, H, and G respectively. The slots" A34 -and- -35 permitthe rollerJ to movetowa-rdi theainking pads whenY downward pressureis broughttovbear Aupon the-frame A. j

In Figs. 1- and 2, I indicate ahandle Lw-hich is secured Vto the.frameAfjbye a screw-.53.The

screw is received-in a; boss 54 that-is integral with the-:plate l andprojeotsvthereabove.;l The Y handle is longenough-tdbe readilygrasped bythe hand` of the user. As already stated the device is'shown on agreatly Yenlarged scale :in the drawing and'inv actual practice theroller J will be approximately one inch in diameter. Ido not wish,however., to be confined to-fany exact measurement. Y

The roller J may have; eanyedesired design,

In Fig. 1,-I disclose a simplemechanism for indicating each-revolution of` theroller.` A-spring clip55Yis-secured tothe inner surface offthe side Wall 2v and carries aprojection that-bears 'againstk the adjacent send, of the roller.
